THE CHEMOURS COMPANY Investor Presentation September 2026

This presentation contains forward-looking statements, within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, which involve risks and uncertainties. Forward-looking statements provide current expectations of future events based on certain assumptions and include any statement that does not directly relate to a historical or current fact. The words "believe," "expect," "will," "anticipate," "plan," "estimate," "target," "project" and similar expressions, among others, generally identify "forward-looking statements," which speak only as of the date such statements were made. Forward-looking statements are based on certain assumptions and expectations of future events that may not be accurate or realized, such as guidance relying on models based upon management assumptions regarding future events that are inherently uncertain. These statements are not guarantees of future performance. Forward-looking statements also involve risks and uncertainties including the outcome or resolution of any pending or future environmental liabilities, the commencement, outcome or resolution of any regulatory inquiry, investigation or proceeding, the initiation, outcome or settlement of any litigation, our ability to maintain an effective internal control over financial reporting and disclosure controls and procedures, changes in environmental regulations in the U.S. or other jurisdictions that affect demand for or adoption of our products, changes in regulations in the U.S. or other jurisdictions that could impose tariffs or additional costs on products we either sell or need to purchase, anticipated future operating and financial performance for our segments individually and our company as a whole, business plans, prospects, targets, goals and commitments, capital investments and projects and target capital expenditures, efforts to resolve outstanding or potential litigation, including claims related to legacy PFAS liabilities, plans for dividends, sufficiency or longevity of intellectual property protection, cost reductions or savings targets, plans to increase profitability and growth, our ability to develop and commercialize new products or technologies and obtain necessary regulatory approvals, our ability to make acquisitions, integrate acquired businesses or assets into our operations, and achieve anticipated synergies or cost savings, among others, all of which are subject to substantial risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such statements. These statements also may involve risks and uncertainties that are beyond Chemours' control. Matters outside our control, including general economic conditions, geopolitical conditions, changes in laws and regulations in the U.S. or other jurisdictions in which we operate, and global health events and weather events, among others, have affected or may affect our business and operations and may or may continue to hinder our ability to provide goods and services to customers, cause disruptions in our supply chains such as through strikes, labor disruptions or other events, adversely affect our business partners, significantly reduce the demand for our products, adversely affect the health and welfare of our personnel or cause other unpredictable events. Additionally, there may be other risks and uncertainties that Chemours is unable to identify at this time or that Chemours does not currently expect to have a material impact on its business. Factors that could cause or contribute to these differences include the risks, uncertainties and other factors discussed in our documents filed with or furnished to the U.S. Securities and Exchange Commission (“SEC”), including in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2026 and our Annual Report on Form 10-K for the year ended December 31, 2025. Chemours assumes no obligation to revise or update any forward-looking statement for any reason, except as required by law. We prepare our financial statements in accordance with Generally Accepted Accounting Principles (GAAP). Within this presentation, we may make reference to Adjusted Net Income, Adjusted EPS, Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow, Free Cash Flow Conversion, Total Debt Principal, Net Debt and Net Leverage Ratio which do not have any standardized meaning as prescribed by GAAP and are considered non-GAAP financial measures. The Company includes these non-GAAP financial measures because management believes they are useful to investors in that they provide for greater transparency with respect to supplemental information used by management in its financial and operational decision making. Management uses Adjusted Net Income, Adjusted EPS, Adjusted EBITDA Margin, and Adjusted EBITDA, which adjust for (i) certain non-cash items, (ii) certain items we believe are not indicative of ongoing operating performance or (iii) certain nonrecurring, unusual or infrequent items to evaluate the Company's performance in order to have comparable financial results to analyze changes in our underlying business from period to period. Additionally, Free Cash Flow, Free Cash Flow Conversion, Total Debt Principal, Net Debt and Net Leverage Ratio are utilized as liquidity measures to assess the cash generation of our businesses and on-going liquidity position. These measures may not be comparable to similar measures presented by other companies and should not be viewed as a substitute for measures reported under GAAP. Accordingly, the Company believes the presentation of these non-GAAP financial measures, when used in conjunction with GAAP financial measures, is a useful financial analysis tool that can assist investors in assessing the Company's operating performance and underlying prospects. This analysis should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. This analysis, as well as the other information in this presentation, should be read in conjunction with the Company's financial statements and footnotes contained in the documents that the Company files with the SEC. The non-GAAP financial measures used by the Company in this presentation may be different from the methods used by other companies. The Company does not provide a reconciliation of certain forward-looking non-GAAP financial measures to the most directly comparable GAAP reported financial measures on a forward-looking basis because it is unable to predict with reasonable certainty the ultimate outcome of unusual gains and losses, potential future asset impairments and pending litigation without unreasonable effort. These items are uncertain, depend on various factors, and could have a material impact on GAAP reported results for the guidance period. For more information on the non-GAAP financial measures, please refer to the reconciliation tables beginning on page 31 of this presentation and materials posted to the Company's website at investors.chemours.com. This presentation has been prepared by the Company for information purposes only and is being furnished on a confidential basis solely for use by the recipient in making its own evaluation of the Company and its business, assets, financial condition and prospects.

The EU F-Gas Regulation has steadily tightened HFC quotas since 2015 to support the EU’s 2050 climate-neutrality ambitions helping drive the automotive industry's HFO transition years before the U.S. AIM Act. The AIM Act empowers the EPA to reduce US HFC production and consumption ~85% by 2036, driving customers to transition to low GWP HFO refrigerants, including Opteon™ as one of two viable choices. The phasedown is organized in a stepwise manner, utilizing an allowance allocation and trading program; GWP stepdown based on CO2eq allocation. Quota Stepdowns Across Major Regions Developing nations aligned with Kigali A5 begin regulatory-driven stepdowns in 2028, creating greater addressability for OpteonTM products

12 TSS: A Clear Path to Growth Ahead Opteon™ Sales Growth Driven by Existing Core Markets & Strengthened by Ongoing R&D Investments Opteon™- specific layered portfolio of thousands of international patents protects Opteon™ sales across molecules, blends, applications, and manufacturing processes. Opteon™ YF (R-1234) is covered by an international patent portfolio for R-1234yf products having expiration dates through the end of the decade. Patents covering other aspects of Opteon™ refrigerants including blend compositions, manufacturing, applications, and other R-1234yf compositions extend into the late 2030s, with processes in place to establish new IP protected products in the future. As quota stepdowns occur in key markets, TSS is positioned to grow through Opteon™ IP protection and focused exposure to high-growth markets, including the stationary aftermarket and data center cooling, supporting continued GDP+ growth and 30%+ margins for its core markets. Innovation-driven R&D advancements (e.g., two-phase immersion cooling, Next Generation Refrigerants), paired with further regulatory transition beyond core markets, enable TSS to deliver results above its core business. New product offerings add potential new layers of IP protection in high-value end markets and extend market reach.
